Evergreen Bio – Brain & Neurons

[Audio] Evergreen Bio – Brain & Neurons Interactive Animated Video Script by Aakriti 🌸.

[Audio] Introduction Welcome to Evergreen Bio! I'm Aakriti, and today we’re learning about the human brain and neurons. Your every move — blinking, running, even smiling — begins from this magical organ! 🧠.

[Audio] The Nervous System Our nervous system is like the body's control network. It has two parts: 1️⃣ Central Nervous System (CNS) – Brain & Spinal Cord 2️⃣ Peripheral Nervous System (PNS) – Nerves connecting rest of body.

[Audio] The Neuron Neurons are tiny units carrying messages in electrical form. Parts: - Dendrites: Receive signals - Cell Body: Controls neuron - Axon: Sends messages Fun Fact: The brain has nearly 100 billion neurons! 🌟.

[Audio] Types of Neurons Three types: Remember with S–M–I = Smart Monkeys Investigate 🐒 1️⃣ Sensory Neuron – Sense → Brain 2️⃣ Motor Neuron – Brain → Muscles 3️⃣ Interneuron – Connects the two inside CNS.

[Audio] Reflex Action Reflex actions are automatic. Example: You touch a hot cup ☕ and pull back instantly. Controlled by spinal cord, not the brain!.

[Audio] The Brain The brain is the command center. Parts: 1️⃣ Cerebrum – Thinking, learning, memory 2️⃣ Cerebellum – Balance, movement 3️⃣ Medulla – Breathing, heartbeat Extra: Hypothalamus – Hunger, thirst, temperature.

[Audio] Memory Trick Use this to remember parts: 'Cats Have Curious Minds' 🐱💭 C – Cerebrum (Thinking) H – Hypothalamus (Hunger) C – Cerebellum (Balance) M – Medulla (Heartbeat).

[Audio] How It Works Together Message flow: Hand → Spinal Cord → Brain → Muscles Sensory neurons send → CNS processes → Motor neurons act! Fun Fact: Nerve messages travel at 250 mph! ⚡.

[Audio] Quick Quiz 1️⃣ What connects brain & body? → PNS 2️⃣ Which part controls balance? → Cerebellum 3️⃣ Trick for neuron types? → S–M–I 🧠.

[Audio] Conclusion Now you know how your brain & neurons work like a super team! 💪 Keep learning, stay curious, and your brain will grow stronger. Created by Aakriti 🌸.
